Specification of Letters Patent.

Patented Aug. 23, 1921.

Application filed December 12, 1911.- Serial No. 665,315.

To all whom it may concem:

Be it known that I, FREDERICK A. HART, a citizen of the United States,residing in J ersey City, in the county of Hudson and State of NewJersey, have invented certain new and useful Improvements in Combined Tpe-writing and Computing Machines, of WllICh the following is aspecification.

This invention relates to combined type-- writing and computingmachines, and is illustrated in connection with a machine of theUnderwood-Hanson type.

In these machines, it is customary for the operator to copy upon thework sheet the result of a computation which appears upon the computingwheels. It is possible, 110wever, for the operator to make an error intranscription, thus leaving it always uncertain whether the resultwritten at the foot of a column is absolutely correct or not.

One of the principal objects of the present invention is to avoid thisdifliculty, and to insure that the same result shall be written as shownon the dial wheels or devices.

To accomplish this result, I provide a power-driven device, preferablyconnectible to an electric motor, which mechanically operates the typesto print on the work sheet the number which appears on the dial wheels,so that the necessity is avoided of depending upon the accuracy of theoperator. In the preferred form of the invention, the numeral type-barsare operable by spring-driven operators, which however do not interferewith the usual manipulation of the numeral keys of the typewritingmachine. The spring-driven operators. are then automatically reset bythe action of the power-driven devices thereon. Suitable selectingmechanism is provided in connection with the dial wheels to determinewhich digits shall be written in the digit columns and the position ofthe typewriter carriage controls the denomination of the dial wheelwhich selects the type to be printed in any digit column. In otherwords, the carriage determines which dial wheel shall act, and in whatcolumn the digit shall be printed, while the dial wheel determines whichdigit shall be used.

There are employed ten type bar opera tors, one for each numeral typeincluding the 0 type; and each dial wheel has means for selecting ordetermining which of said ten operators shall be made effective. A snailcam is provided upon each dial wheel, and a selector is moved by saidcam in one direction and returned by a spring. The construction is suchthat when the dial wheel 1s m any rotative position, the selector is inPOSlt-lOIl to engage or control that type operator which corresponds tothat digit upon the dial wheel which appears at the sightopenlng. Theselectors are hence ready to cause the operations of the types; and adog upon the carriage operates in succession a series of devices whichcause said type operators to become effective in succession. As

each type operator works, the type is printed and the paper carriage isfed, thus bringing lnto operation the device which causes the succeedingnumeral type to print, and soon.

The power-driven printing devices are preferably normally out of use, topermit the machine to be operated in the usual manner; but by pushing alever they may be brought into use at will. Said operators may control.either the usual numeral type-bars, or if desired an additional set oftype-bars may be provided, each carrying a specially designed typedifferent from the corresponding numeral type of the typewriter, so thatthe result of the computation will be written on the work sheet with thespecial type, thus showing that the result was written mechanically bythe machine itself, and not by the user.

Other features and advantages will hereinafter appear.

In the accompanying drawings,

Fig. 12 is a perspective view illustrating the connection between atype-operating link and a motor-driven shaft, whereby the movements ofthe type to and from the work sheet are effected or controlled.

The typewriting mechanism comprises alphabet type keys 1 and numeralkeys 2, all of which are mounted upon levers 3 fulcrumed at 4 andconnected by means of bell cranks 5 to type-bars 6, to swing the latterup to print against-the platen 7, which is mounted upon a carriage 8,the latter being driven by a spring barrel 9, and having a rack 10 tomesh with a pinion 11, which drives an escapement wheel 12. Theescapement wheel is controlled by dogs 13, 14, operated by a frame 15 onwhich is fixed a universal bar-16 that isactuated by heels 1'? on thetype-bars in the usual manner in an Underwood typewriting machine.

The numeral keys 2, (except that key which is connected to th 0 type)also actuate a pin-setting mechanism of the computing machine. Thenumeral keys have pendent stems 18 to engage and depress arms 19provided upon horizontal rock shafts 20, which extend rearwardly beneaththe key levers and form part of linkages 21, which depress pins 22todetermine how far the dial wheels are to be rotated. These pins 22extend in rows from front to back of the machine, each row carried upona bar 23, which at its forward end has a rack 24 in mesh with a pinion25 on the dial wheel 26; the operation being disclosed in my pendingapplication No. 466,836, filed December 10, 1908 (now Patent No.1,270,411, dated June 25,1918).

There is one row of pins 22 upon each of the rack bars 23, and there isone rack bar for each denomination. Each row of pins must be liftedabove the others in order to come into the paths of the linkages 21, andthis lifting of the pin rows is effected by a dog 27 upon the typewritercarriage 8, which during the letter feeding movement of the latter,'ngages and lifts one by one the usual jacks 28, which are fulcrumed at29, and at their rear ends depress rods 30, which are connected bylevers 31 wit-h linkages 32, whereby the pin-carrying rack bars 23 areelevated and dropped in succession as the paper carriage 8 feed along;so that when a digit is written in any place in a column on the worksheet, the rack bar 23 of corresponding denomination is lifted, and apin 22 thereon is depressed, according to the key struck.

After the number has been written and the corresponding pins depressed,the racks 23 having dropped again to normal posi tions, the generaloperator is reciprocated to carry the number into the dial wheels 26.This general operator comprises a pair of racks 33, one at each side ofthe machine and connected by cross-bar 34, which engages the depressedpins 22, to drive forwardly theracks 23 and turn the dial wheels 26;while said cross bar subsequently engages teeth 35 and carries therack-bars 23 back to initial positions. The racks 33 are connected byidle pinions 36 to a pair of segments 37 fixed upon a rock-shaft 38extending horizontally across the machine, and at its ends journaled inthe side walls thereof. There is also connected to one of the racks 33 atens-carrying mechanism comprising an idle pinion 39 meshing with apinion 40, the latter suitably connected to a square shaft 41, whichcarries means to assist in carrying tens from one dial wheel to another,as set forth in said application.

From the foregoing, it will be seen that numbers may be written in thecolumn on the work sheet, and concomitantly added upon the dial wheels.The latter may be held by spring detents 42 engaging gears 43 fixed onthe dial wheels. Upon the return of the racks 23 and the generaloperator 33, a universal plate 44 is lifted beneath the pins 22, toreset to normal positions those which have been depressed.

It will be seen at Fig. 3 that the clutch tends constantly to close, butis restrained by a trip pin 52, which stands normally in the pat-hof alug 53 on a ring or segment 54, which encircles said hub 50, andrestrains a clutching-roll-55, which normally occupies a recess56, butis urgedby a spring 57 into clutching connection between said hub 50 anda cup 58, which is fixed to said shaft 51. The restraining trip 52 maybe withdrawn by depressing a key 59, Fig. 8, usu-- ally provided on themachine and having a stem 60 pivoted to a lever 61, which depresses oneend' of a lever 62, lifting up the other end 63 thereof, said end 63engaging a slot 64 in the trip pin 52 to lift the same out of engagementwith the ,lug 53. Hence by pressing said key 59, the shaft 51 isclutched to the revolving worm wheel 49, and makes a completerevolution. Upon said shaft 51 is a. crank 65 (Figs. 7 and 9) having awrist or block 66 engaging a vertically slotted slide 67, which has ahead 68 engaging a yoke 69 secured to one of the general operator racks33, Figs. 3 and7. The slide 67 has horizontal supporting and guidingarms 70 working in bearings 71. Upon release of the key 59, the trip 52drops into the path of the lug 5 3 and arrests the ring 54 and roll 55,so that the shaft 51 comes to rest with the general operator 33 innormal position.

All of the type-bars, including the bar which carries the 0 type, areoperable not only by the keys, but also by a source of power, for thepurpose of writing on the work sheet the number which is indicatedby thedial wheels. For this purpose, each type bar is provided with a specialoperator in the form of a slide 72, having at its upper end a hook 73,to bear down a pin 74 against the platen; but it is normally re--strained fromdoing so by a wrist 83, which rests upon the high part of asnail or other cam 84, which is loosely mounted upon said power-shaft 79, and is connected-thereto by a normally open clutch. This clutch issimilar in construction and operation to the one heretofore describedbetween the shaft 51 and the worm wheel 49; and it has a lug 85 (Figs. 3and 6) similar to lug 53 and normally restrained by a latch 86, whichhas.a returning spring 87; there being one clutch for each of the typebar operators 72. The clutching ball or roll 88, similar to roll 55,works between a loosely mounted shell 89 and a boss 90, which is fixedon the power-driven shaft 79, and corresponds to.

the part 50. A spring 91, corresponding to spring 57, tends to close theclutch. The cam 84 is fixed by a screw 92 to the shell 89. Hence whenthe lug 85 is released, the cam 84 turns clockwise at Fig. 12, the wrist83 drops off the top part of the cam, and the spring pulls down theoperator 72, the key stem 18 and the type bar, causing the latter tostrike the platen. The clutch and cam continue to rotate, forcing thewrist 83 again to the high part of the cam and returning or permittingthe return of the type bar to normal position under the influence of theusual spring 93, Fig. 2.

The shaft 79 is connected to the main power-shaft 47 by a train ofgearing comprising pinions 94 and 95, the latter upon a vertical shaft96, Fig. 6, which carries at its end a pinion 97 in mesh With a pinion98 on a horizontal shaft 99, which carries a pinion 100, in mesh'with apinion 101 on the' power-shaft 47. By this means, the shaft- 7 9 may becaused to rotate at a speed preferably less than that of the power shaft47.

There are one clutch and one latch 86 for each of the ten numeral typebars. The control over the latches 86 is divided; the paper carriage 8of .the typewriter determining type bar is to be operated, and the dialor computation wheels 26 selecting the type bar which is to operate.

The carriage 8 of the typewriter exercises its control through the dog27, jacks 28, links 30 and levers 31, each of the latter having adownwardly extending arm '102, which by means of any suitableconnections (illustrated as includlng a rod 103 (Figs. 3 and 10), lever104, link 105, bell-crank 106 and link 107) may operate one of a set oflevers 108 to lift a selector 109 to release one of the latches 86.These latcheshave arms 110 which overlie a set of linkages in positiontobe lifted by any thereof when the linkage is operated by the selector109. These linkages include parallel links 111 and 112 pivotallyconnected by bell cranks 113, 114 (Fig. 6), so that the links 111 willmove substantially vertically. T he selectors 109 are shiftableindividually to positions to engage teeth 115 thereon with any one ofthe links 111, and merely act as selecting interponents between thelevers 108 and the set of linkages. The raising of a lever 108 raises aselector 109 of the same denomination, which in turn raises a link 111so that jack 28, the members 30, 31 and 102 to 109 inclusive, are calledinto action to operate one of the linkages 111-114 to lift one of thelatch arms 110, and permit the associated clutch to operate and thecorresponding type-bar to be thrown to the platen.

It will be understood that at any position of the carriage within thecomputing field, any type-bar may be operated; and the method wherebythe computing wheels select the type-bars will now be explained. Thereis one of the selectors 109 for each of the dial wheels 26. At Fig. 3,the selector 109 is illustrated in position for controlling theoperation of the 0 type-bar; but it is shiftable to the right toposition for engagement of any of the remaining nine linkages, so thatit may control the operation of any of the numeral type bars.

The shifting of the selector 109 is effected bya snail cam 117, which isfixed to its associated dial wheel 26; and a follower 118 is held by aspring 119 against the edge of said cam to swing to and fro as the dialwheel revolves. An arm120 of this follower is connected by a link 121 toa lever 122, which has a pin-and-slot connection at 123 to the selector109; the latter having preferably a foot 124: to slide on a table 125;and the lever 108 having a pinion 126 to engage and lift said selector109 in any position to which the same may be adjusted by the snail cam117. I

The next movement. of the dial wheel 26 in clockwise direction at Fig.3, will permit the follower 118 to snap off from the high part ofthe camto the low part thereof, the spring 119 thrusting the selector 109toward the right, so that its tooth 115 may engage the extreme righthand linkage, the latter having a tooth 116 to engage the latch 86,which is associated with the 1 key stem 18, which is at the extreme leftof Fig. 6. As the dial wheel 26 is rotated, the tooth 115 is presentedsuccessively to all of the other linkages; and at any time, it will befound that the tooth controls that linkage Which corresponds with thenumber seen at the sight-opening 127 in the casing of the machine, Fig.3.

The positions of the set of selectors 109 will repeatedly changeduring-the operation of the machine; said selectors being always inpositions to secure printing on the work sheet of the number whichappears on the set of computing wheels at said sight-open- 1n ever thecarriage dog 27 operates a jack 28, the lever 108 is lifted to rendereffective that selector 109 which corresponds in denomination to theoperater jack 28, and hence which corresponds to the denominationalposition of the carriage in the computing column. To illustrate; if thenumber 1325698 appears through the sight-opening 127, the selectingteeth 115 will stand at corresponding positions beneath the linkages1111 14 and if the carriage is then brought into the computing field,the dog 27 will operate the millions jack 28', and the connections(including the transposition device 107) to the millions lever 108, andthat in turn will lift the millions selector 109 to raise the firstlinkage at the extreme right at Fig. 3, thus releasing the first latch86 at the extreme left of Fig. 6, and causing the type-bar 1 to printand return to normal position; the spring 87 serving to reengage thelatch 86 with the dog 85, to release the-clutch at the completion of onerevolution thereof, with the operator 72 in normal position.

The movement of the type bar causes the paper carriage 8 to feed as thedog 27 moves to and depresses the hundred thousandjack 28, and throughits connections the corresponding lever 108 is raised together with thecorresponding selector 109, whose tooth now stands under the thirdlinkage from the right at Fi 3, whereby the third latch from the le t atFig. 6 is released, and the type bar 3 is thrown up to print. Thecarriage again feeds, and the operation continues until the entirenumber is written upon the work sheet which appears at the sightopening.

As the principal use of the device is to write upon the work sheet thetotal of a computation, a lever 128 may be swung forwardly at Fig. 3, tothrust back a link 129 and swing back an arm 130 rising from a rockshaft 131 journaled in the framework of the machine, and carrying aplate or bar 132 having openings or slots 133 for the rods 103; thedescribed movement of the plate 132 causing all of the rods 103 to swingdown out of the paths of the arms 102, thereby silencing ordisconnecting the power-operated printing mechanism.

The motor 45 is preferably intermittent, as set forth in pendingapplication No. 650,700, filed September 22, 1911, now patent No.1,237,900, dated August 21, 1917. Conductors 139 and 135, Fig. 11,leading to the clutch, control switches, as set forth in saidapplication. In order to start the motor when it is desired to write anumber by means of the motor-driven mechanism, a circuit closer 136 isplaced on the link 129 3' From the foregoing, it follows that when--zone and thus outside of the range of the wheels of the register.
